This collection consists of autobiographical essays which center around my father,
my first husband, and my backyard. All of the pieces are recollections, and most occur
either from my study inside the house, or from the deck outside, looking at the yard. The
Preface is the story of how I...
Steroid organoboranes have been found to be useful synthetic
intermediates. Attempted pyrolyses, based on simple trialkylborane
cyclizations, have not yielded C-19 or C-18 functionalized steroids,
but have produced isomerized systems not otherwise available.
Thus, hydroboration of cholesterol followed by pyrolysis at
215° gives 31% of 2-cholestene-6α-ol and 49% of a...
Studies were conducted from 1962 to 1966 to investigate the
effectiveness of several practices in manipulating medusahead
(Taeniatherum asperum (Sim. ) Nevski) infested and/or dominated
ecosystems by releasing competition in favor of perennial grasses.
Several herbicide treatments were evaluated for selective
control of medusahead and cheatgrass (Bromus tectorum L. )...
Purpose of the Study:
The School Health Fair is an experiential method used to supplement classroom theory in a teacher preparation course at the University of Wisconsin-La Crosse (UWL). The purpose of this study was to determine how this method affected student attitude toward teaching. The following null hypotheses were...
Violence and voice seem to be related. In this thesis I detail personal experiences with violence, and then put them into the context of research done about the ways in which violence affects the writing voice, as well as the speaking voice. Helene Cixous' writings about the writing voice and...
This thesis is a collection of essays about Paxton, a
small town in western Nebraska, and an exploration of the
contradictions and complexities found there. It is also a
reflection on the layers of history and connections that
exist not only among families that have lived in these towns
for...
The eruption of Mt. St. Helens provided the
opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their
watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...
Hydrogen cyanamide (CY) induced earlier budbreak, more
uniform and a higher percentage of budbreak in resting
poplar (Populus alba x P. gradidentata, NC 5339) plants.
However, it was phytotoxic to poplar when applied at 0.5 M
or higher concentrations. Percent budbreak increased and
percent dieback decreased when poplar plants were...
Some perennial grass seed crops such as red fescue (Festuca rubra
L.) do not produce a profitable seed crop during the first growing
season. The present establishment method in Oregon for red fescue seed
crops generally entails spring planting which does not satisfy
vernalization requirements for seed production in the...
Apoplastic distribution patterns of atrazine [2-chloro-4-(ethylamino)-
6-(isopropylamino)-s-triazine], glyphosate [N-(phosphonomethyl)-
glycine], the naturally occurring apoplastic leaf solutes, and
the apoplastic dye PTS (trisodium 3-hydroxy-5,8,10-pyrenetrisulfonate)
were compared. Aliquots of sap were expressed from intact
sunflower leaves in a pressure chamber over intervals of 0.2 to 0.4
bars. Three distinct fractions were detected...
